Hinge.



EPHRAIM WITMAN, JR., OF WERNERSVILLE, PENNSYLVANIA.

HINGE Specification of Letters Patent.

Patented June 9, 1908.

Application filed August 10, 1907. Serial No. 387,986.

To all whom 'Lt may concern:

Be it known that l, EPHRAIM WITMAN, Jr., a citizen of the United States, and a resident of Vernersville, in the county of Berks and State of Pennsylvania, have invented new and useful Improvements in Hinges, of which the following is a full, clear, and exact description.

This invention is an improved hinge, more especially designed for window shutters, and being adapted when applied thereto to positively lock the shutter when opened, whereby it will be impossible for the shutter to be rattled by strong winds.

The invention further resides in certain special features of construction and arrangement of parts which will be fully set forth hereinafter and particularly pointed out in the claims.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is aview of one corner of a window in perspective, showing the preferred embodiment of my improved hinge applied to a shutter with the parts of the hinge in a position to lock the shutter against movement; Fig. 2 is a cross section of the shutter just above the hinge when the shutter is closed; Fig. 3 is a cross section on the line 3-3 of Fig. 1; Fig. 4 is a section of the hinge on the line 1 -4 of Fig. 5; and Fig. 5 is a section of the hinge on the line 5 5 of Fig. 4.

My improved hinge enbodies in its construction the usual inside and outside leaves 10 and 11 respectively, which are pivoted together by a pintle 12, the latter being rigidly iixed `to the enlarged portion of the leaf 10 and passing through an aperture in the knuckle of the leaf 11.

The leaf 10 is provided with a projection 13 overhanging the enlarged portion thereof, as shown in Fig. 5, and located at a point intermediate its width, which, in connection with a collar 14 carried by the knuckle of the leaf 11 and having a notch 15, prevents disengagement of the leaves, except when turned at substantially right angles to each other to bring the notch 15 and projection 13 into register. ln this position, the outer leaf 11 and the shutter to which it is attacfhed may be bodily lifted from the inside lea The enlarged portion of the leaf 11 is`constructed with a horizontal extension or arm 16 in substantial alinement with the leaf,

and to the inside face of which is pivoted a latch 17, the latter being provided with a curved wedge-shaped head and a thumbpiece 18 projecting at one side thereof, Which serves to operate the latch and also to act in connection with the top edge of the leaf 11, as a stop when the latch is thrown back to an inoperative'position.

When the shutter is thrown open and brought in contact with the outer wall of the building by turning the latch down, as illustrated in Fig. 1, the wedge-shaped head thereof is forced between the leaves and engages each with a different face. By this l mean that one side face of the latch bears directly on the adjacent face of the leaf 10, and the opposite side face of the latch likewise bears on the arm 16, forming a part of the leaf 11. This action of the latch throws the shutter tightly against the wall and prevents it from being closed or rattled by strong winds. y

The invention as shown and described while being my preferred practical construction may obviously be modified in numerous particulars falling within the scope of the appended claims.

Having thus described my invention, I claim as new and desire to secure by Letters Patent: j

1. A hinge comprising two leaves pivoted together, and means movable between said leaves engaging each with a different face, said means tending to swing the leaves on their pivot.

2. A hinge comprising two leaves having a pintle pivotally connecting them together, and a device pivotally mounted on one of said leaves engaging each with a different face, said device tending to cause the leaves to swing apart on the pintle.

3. A hinge comprising two leaves having knuckles, a pintle pivotally connecting the knuckles of the leaves together, one of said leaves having an arm laterally projecting to the opposite side of the knuckle, and a latch pivoted to said arm adapted to engage the other leaf with its outer and opposite face and tending to swing the leaves apart on the pintle.

In testimony whereof l have signed my name to this specification in the presence of two subscribing witnesses.

EPHRAIM WITMAN, JUNIOR.
